The Perfect Comrades Marathon taper

On this edition of the Ask Coach Parry podcast, we have two similar questions. Scott Giles, with just less than a month to go to Comrades, and Hermo Terblanche want to know about tapering. Scott asked at this stage, heading into Comrades and looking at the taper, should he be tapering as far as distance goes, speed-wise or both. Hermo wanted to know percentage wise for tapering, how much should he cut back in May compared to the mileage he reached in April.
